79 and later Triumphs were wired negative ground, positive hot. Your bike is now wired the same way.
The person who did the relocation may not have been aware of the bike's original positive ground arrangement. I am assuming that they didn't also rewire the Boyer to match?
If the brown wire goes to the negative pole of the battery and the negative pole is then also grounded, as the mechanic would not have had to relocate the battery, the leads to the battery may be original, then the system won't charge.
So, just make sure the red wire is grounded and that all the ground wires link together, not using the frame for the ground (called "bonding"), that the brown wire goes to the negative pole of the battery, and that the negative pole of the battery then attaches to the ignition switch "hot" position.
Triumph old, Triumph new, any Triumph will do.
